Binetti said that based on the Correctional Officer Bill of Rights passed in Annapolis in 2010, non-management employees can have a union representative present if they are interviewed by officials during the review process but cannot have one present during a polygraph test.
The federal Employee Polygraph Protection Act of 1988, which prevents private employers from administering polygraph tests to employees, does not apply to public employees, according to the U.S. Department of Labor. Other public safety agencies also use polygraph tests; Baltimore's Police Department uses them to screen applicants.
Any information obtained through polygraphs or other reviews could be used in disciplinary actions, Binetti said.
Maryland U.S. Attorney Rod Rosenstein said if the polygraphs turn up more admissible evidence of wrongdoing, he would consider prosecution. But he said criminal prosecution is a powerful tool, like a hammer, and "you don't want to use a hammer in every case."
Archer Blackwell, a representative of AFSCME Council 67, which serves officers at the detention center, said polygraph tests and integrity reviews are "probably a good idea" for supervisors at the jail.
But he said officials should "walk very softly" when confronting corrections officers and other clerical and support staff not implicated in the federal indictment.
"Some of the other employees who know they weren't involved, you don't want them to get offended and feel like you're just coming after everyone," Blackwell said. "They need to be handled in such a way that it [isn't] being projected that everyone is corrupt."
Many employees at the jail are happy the corruption has been uncovered, Blackwell said, but some feel supervisors had ignored their concerns about colleagues' conduct. The spotlight on the detention center has been hard on them, he said.
"Everybody just feels like they're just being stepped on, and that is something that shouldn't happen," Blackwell said. "They need a morale-builder."
Maryland Attorney General Douglas F. Gansler, whose office provides legal counsel to the corrections department, said the corruption "clearly should be taken seriously." He said the administrative steps being taken by Maynard to discover how it occurred are appropriate.
"The allegations are almost surreal," he said Friday. "The notion that four different correctional officers can get pregnant from one prisoner? Most people would think that could never happen."
Gansler said he is confident that federal prosecutors will pursue the case successfully, but state leaders must also determine how to prevent something similar from happening again.
"It seems like people are taking it all seriously, and certainly the attorney general's office is," Gansler said.
White was moved out of the detention center just before the indictment was unsealed, Binetti said, but the department would not release his location for security reasons.
Four other inmates with Black Guerrilla Family ties have been moved since. More than two dozen have been transferred out of the jail in the past three months, Binetti said.
Maynard is moving to the jail from his office at the Department of Public Safety and Correctional Services in Towson.
